These proceedings contain 106 papers which reflect the current research and advances made in the applications of numerical methods to geotechnical engineering problems. The papers are divided in six sections: Constitutive relations for geological materials: formulation and verifications; Instability and strain localisation in geomaterials; Modelling of reinforced soil; Modelling of transient/coupled problems; Numerical Algorithms: formulation and performance; Application of numerical techniques to practical problems. Many new developments on a wide variety of topics have been reported. These include: Partially saturated soils, transition from fully to partially saturated state and vice versa, strain localistation, environmental geomechanics, parallel computing, neural networks and applications to tunnels, embankments, slopes and foundations. A number of these advances will form the basis of research and development in the future. A wealth of information is available in the proceedings which should be of interest to researchers as well as practising engineers.
